Biomarkers for the detection of necroptosis.

Necroptosis has been extensively studied recently, and the receptor-interacting kinase 3 (RIP3 or RIPK3) and its substrate, the pseudokinase mixed lineage kinase domain-like protein, have been discovered to be core components of this process. Classical necroptosis requires RIP1 (or RIPK1) for the activation of RIP3 through the induction of RIP1/RIP3 necrosomes. Increasing evidence from genetic and pharmacological studies has been expanding the view that necroptosis plays important roles in the etiology and/or progression of many human diseases, such as pancreatitis, ischemic injury, and neurodegenerative diseases, among others. Ongoing progress in translational research about necroptosis has highlighted the increasingly important need for the identification of biomarkers for use in disease diagnosis, monitoring, and drug development. This review presents a discussion of the current status of biomarkers that can be used to detect necroptosis both in vitro and in vivo.
